I’ve got fwsy so I’ll have a look later. One thing I did find with the recipes was that the methods described never gave me sufficient development. Really struggled to get a good structure, which may contribute to things collapsing. They’re definitely not foolproof recipes.
I've done that recipe before but I'm sure I just did the whole long proving in the fridge. Otherwise there's too much activity and the loaf doesn't have any energy to spring when you bake.
